To all whom it may concern:

Be it known that I, CARL M. Yonnn, a citizen of the United States, and resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Universal Wiring-Machines, of whlch I hereby declare the.

. following to be a full, clear, and exact deand articles made therefrom, irrespective of the contour of the sheet metal edge or shape of the article.

Another object of the invention is to provide a plurality of metal bending devices, certain of which are bodily movable rela tive to each other, whereby the edge or edges of metal strips or sheets and sheet metal articles, irrespective of the contour thereof, may be bent up,vbeaded or reinforced.

Other objects of the inventionwill be apparent, to those skilled in the art, from, the following description, in which Figure 1 is an elevation of amachine for reinforcing metal strips or sheets and articles made therefrom, embodying my invention.

Fig. 1 is a perspective view of a machine embodying a slightly modified form of the invention. V I r Fig. 2 isa fragmentary elevation, somewhatenlarged, of the machine shown in.

Figs, 5,6, 7 S and 9 are sectional views showing the action the bend g devices.

Figs. 10, 11, 12 and 13 are front, side, rear and top views, respectively, of one of the shaping elements.

Fig; 14 is a detail view of the final shaping devices. 1

t Fig. 15 is a detail view of the preliminary bending devices. 7

Fig. 16 is a detail view of the clutch.

Reinforcing of the edge of the metal is accomplished by bending over the metal along its edge into a bead or by feeding with the metal a wire and bending orwrapping the-metal therearound. In the preferred form of construction, a wire offthe desired size .is fed with the metal sheet or article to the machine and the metal adjacent the edge thereof is bent around and in snug engagement with the Wire.

In the drawings, A indicates a suitable standard or support. A indicates a frame fixed, in any well known manner, to or upon the standard .A. The frame A is preferably provided with two spaced upright members a, (4, having suitable bearings C to receive nd support a pair of upper and lower shafts. B, B.

The shafts B, B, extend at one side of the frame A beyond the adjacent upright memher a for a purpose to be later set forth; The mechanism for driving one of said shafts, preferably the lower shaft B, may

consist of gears B B B and B (serving as reduction gearing), a belt pulley B and a suitable clutch'mechanism D. The clutch may comprise pivoted arms D and friction band segments D, adapted to be operated by a swinging lever D link D rock arm D rod D and foot lever D'. D indicates a spring connected at its opposite ends to the foot lever D and standard A and tending normally to maintain the leverclevatedand the clutch in inoperative position. The foot lever D" is adapted to be moveddownwardly; when so operated it throws in. the clutch D and connects the pulley B to the shaft B to drive the latter.

D D indicate a pair of spur gears fixed to the shafts B, B, respectively, and meshing with each other. Thegears D and D arepreferably ofthe same, size and serve as driving connections to drive the shaft B fr m the shaft 13 at the same rate of speed.

C, C indicates a pair of rolls or bending elements, respectively, fixed to the extended ends of the shafts B, B. The rolls are shaped for coiiperation and service to give the edge of the metal sheet E a preliminary bend, see Figs. Sand 15. As shown in this latter figure, the roll C is formed with a groove to provide for the feeding of a wire E with the sheet metal E.

S indicates devices for adjusting the shaft B endwise to provide for varying sizes of wire and thicknesses of metal which may be fed between the rolls 0, C. The adjusting devices S preferably comprise a rod 1, rotatably mounted in a bearing in one of the uprights a. The inner end of the rod 1 is provided with screw threads and fits a screw threaded opening formed in a lug 2 which is fixed to the shaft B. The outer end of the rod 1 is shaped toreceive a suitable tool, such as a screw driver, to turn the rod. When the rod 1 is rotated, the screw threaded portion acting on the lug 2, will move the latter in one direction or another, according to the direction that thegrod is rotated, to adjust the shaft B.

The bearings C? for the shaft B are preferably movable vertically for assemblyan'd disassembly purposes and also to permit adjustment of the bending elements C, C. As shown, in Fig. 2, the uprights are cut away and open at their upper ends to receive the bearing block's C C indicates a plate mounted upon the top of each upright a and formediwith a screw threadedopening 3. G indicates a rod provided with screw threads and extending'through the opening 3. The lower end of the rod C bears against the adjacent bearing block C and the upper endof the rod C is provided with a crank or handle,-by means of which the rod can be turned. The bending elements C, C, are spaced from each other a suflicient distance to receive the metal sheetiand feed it for-. wardly while bending its edge laterally. In

the eventthe bending elements. CfC do not ence, one edge of theplatform is bent down wardly, as shown at 4 and secured in any Well known manner to the frame A. F indicates a guide arranged in a position relative to the platform E and bending elements C, C,'to guide the work E to the latter. The

guide F is preferably connected to a rod 5 which extendsthrough an opening formed in the ad acent upright a. The rod'5 is preferably provided "with screwthreads to tak nuts 6, which, by engagement with the opposite sides of the upright a, secure the rod 5 thereto. By loosening thenuts 6, the rod 5 can be adjusted endwise in the opening to position the guide in proper relationship to the bending elements C, C. p

p 7, 8, 9, indicate, as entireties, sets of bending devices for progressively bending or forming the upturned metal edge into final shape and around a wire E when the latter is to be used for reinforcing the metal edge. The bending devices-7, 8, 9, are'preferably mounted to bodily move or slide laterally on a base G'relati'vely to each other and the bendingelements C, C, about an axis which is preferably arranged slightly in front of but agclose to a line cutting the axes of the bending elements C, C, as is possible, and also to rotate on said base, whereby they automatically accommodate themselves to the shape or contour of the sheet metal edge being bent,"beaded or reinforced. Of these bending devices, H, I, indicate a pair of supports slidably mounted upon the base G. Each support H, 1, preferably comprises upper and lower plates 10, 11, engaging the upper and lower faces of the base G and sets of connectors 11 which extend through slots 9 in the base G and connect the plates 10, 11, together. Each connector 11 preferably comprisesa screw 11 and sleeve 11 therefor, the sleeve serving to maintain the adjacent plates spaced apart and out of binding engagement with the opposite faces of th base G. V The guides for each support H, I, preferably comprise a pair of substantially'semicircular ball races 12 formed in the base G and arranged'concentric to each'other, races 12 formed in the under faces of the plates 10, (one racein each plate),'corresponding to the curvature of the races 12, and a series of balls'13 between each pair of races 12, 12. The balls 13 cooperate with the walls of the races to guide and control the direction of movement of the supports H, I, and at the same time serve as anti-friction hearings to permit easy movement thereof. The slots 9 are elongated and curved concentric to the guides or races 12 to permit unobstructed movement of the connectors 11*. As shown, the connectors. 11 and plates 11 serveto maintain the plate 10 in operative relationship with the base GI 14 indicates a standard having a foot 14: which is pivotally mounted upon the support H in any well known manner, but preferably'by a shaft 8 having a reduced screw threaded end fitting a screw threaded 'opening laterally from the standard 14 and arranged to slidably support a bendingelement H The bracket 16 is preferably of polygonal shape in cross section and the opening through the bending element H* is vices 7 is swingable about the shaft 8 and also movable or slidable transversely of the direction of movement of the metal E. The bending devices 7 could be-arranged to rotate on an independent pivot, but owing to lack of space between the bending elements G, C" and 8 8 I prefer to mount them on the standard 1% of the bending devices 8. Due

to the movement of the bending element H transversely and relative to the elements C, C and 8, 8'", adequate provision is made for adjustment thereof to insure its cooperation with the latter sets of bending elements.

Of thefinal bending devices 9, 1 indicates a standard having a foot 1 The foot I is rotatablysecured to the support 1, preferably in the same manner that the standard 14 is rotatably secured to the supportH. 1 indicates a pair of stud shafts extending laterally from the standard I and carrying a'pair of bending elements 9, 9", which serve to bend the metal edge into final form. Thebearing for the upper shaft 1 is preferably adjustable to permit the bending elements to operate upon different thicknesses 'of metal and sizes of Wires. For this ptrposc the standard I is formed with'a guideway 17 to receive a vertically movable bearing block. 18 indicates a plate extending across and secured to the upper end of the standard I by suitable cap screws 18. The plate 18 is "formed with a'screw threaded opening through which extends a screw threaded rod 19. At its lower endthe rod 19 is adapted to engage'the bearing block. By operation of the rod 19, the space s between the bending elements 9%9 may be adjuste'd'as conditions may requirei From the "foregoing description it will be seen that'the'bending devices 7, 8 and 9 are bodily'movable or slidable relative to each other and the-bending elements C, C, prcterably about a common center, and are also rotatable or swingablo. I

"In the operation of the machine, the sheet metal E and wire E are presented to the bending elements C, C. As they pass theretlirough, the metal edge is bent up to the position shown in Fig. 6. The bent-edge passes into and through the die H the walls of which bend the metal edge to the position shown in Fig. 7. From the die H" the metaledge passes'between the bending elements 8 8*, by whichit is bent to the position shown in Fig. 8, and then between the bending elements 9, 9 which bend the metaledge into final shape, as shown in Fig. 9. there the free edge of the metal is curved, as shown in dotted lines in Fig; 3, the bending devices will move or slide laterally and also rotate to accommodate themselves to the c act shape, contour or curvm ture of the free-edge of the metal sheet. As the bending devices both rotate and move laterally they will adjust themselves to an edge which is curvedon a relatively large or small radius. As shown in Fig. 3, the bending elementsC, C are disposed ina vertical plane which is substantially midway between the opposite ends oftravel or movement of the bending devices 7, 8 and 9; Ac cordinglv, the bending devices will accommodate themselves to metal sheetshaving edges curved in either direction, also sheets having compound curved edges or both curved and straight edges.

In Fig. 1 Ihave shown a modified form of construction in whichthe bending ele' ments 7, 8 and 9 are slidably and pivotally V i ounted. on a-vertically arranged plate or table G, instead of a horizontal base Ga In this form of construction .I prefer to form the adjacent upright aand plate G integral as shown in Fig. 1. This modified form of construction is particularly adapted fforreinforcing' the edges or circumferential rim s of metal articles, such as funnels, tubular members, cans and receptacles. To those skilled inthe art of making mechanism of the class described, many alterations in construction and widely difl er ing embodiments and applications of my invention will suggest themselves, without departing from the spirit and scope thereof. My-disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting.
